Looks very good. I am in need of something like it. One (may be stupid) question: how is the sand paper attached to the drum? Is it simply glued to it? WHic kiund of glue is used and when you need to change the sand paper how do you do it?

Thank you very much for so many encouraging comment.Here is the answers to your questions.
– Sand paper is attached with double sided tape
– My pleasure to share the design. SketchUp mode has been uploaded as ” Thickness sander ” by Vagabond55
– Bearing support is the solution to compensate the shift of the contact point as the table angle changes.
Since I do not like to apply any twisting force to the table, height adjusting bolt shall not locked to the table.
– I regret no pic is taken during the build process.
